Air, pipe, head, float, type

The main types of the air pipe head of pontoon type oil tank, air pipe head and pontoon type water tank are divided into two parts:

D, DS type pontoon, oil tank, air pipe head, -D, DS float, oil tank, breather cap

E, ES pontoon type water tank, air pipe head, -E, ES pontoon type water tank, breathable cap

Brief introduction to the role of air pipe head in pontoon type oil tank air pipe head water tank:

Marine float type air pipe head, ballast tank air cap on the ship is mainly through the suction and pressure in the tank breathing is close to the atmospheric pressure, so the pressure is kept within the design pressure of the tank, also can prevent water, rainwater, Mars enters tanks while preventing debris into the air pipe to the tank waves in.

Float Type, Air, Pipe, Head, float air pipe head / float type breathable cap:

Float type oil tank breather cap float water tank vent cap applicable area:

Type ballast tank air cap /D type float type oil tank air pipe head ---- oil tank dedicated to float type oil tank air pipe head /D buoy type D (upper cover is closed, and the built-in fire network)

For example: daily fuel tank air pipe head, settling tank air pipe head and oil tank air pipe oil tank air pipe head, fuel oil drain tank air pipe head, lub oil drain tank air pipe head

Air head /E type float type ballast tank air cap /E type float type oil tank air pipe head ---- dedicated to water tank pipe type E pontoon boat (the side cover is not closed, and built-in insect nets)

Such as:

The cargo air pipe head / tail tank air cap, cabin air cabin air cap, joint / ballast / air joint ballast tank fresh water tank air cap, air pipe head / fresh water tank air cap, compartment air / air cap, joint air / air cap joint chain locker

Special functions of marine pontoon type air tube head / float type breather cap:

The head of the oil tank, the air pipe head / the water tank and the air pipe head can be automatically closed, so it is also called the self closing oil tank, the air pipe head / the self closing water tank and the air pipe head. This feature is accomplished by its inner parts: stainless steel float / stainless steel float.

When the environment is bad, the sea water or rain water enters the air cap, and when it is too late to discharge, the float is jacked up. After the float is raised, the water cannot enter into the air duct, thereby isolating the possibility of entering the cabin

D, DS float type oil tank, air pipe head and E, ES pontoon type water tank, air pipe head shape is expounded:

D, DS type oil tank, air pipe head / float type oil tank, breathable cap, 50-80A for unilateral ventilation

E, ES type oil tank, air pipe head / float type oil tank, breathable cap, 50-80A for unilateral ventilation

D, DS type oil tank, air pipe head / float type oil tank, breathable cap, 80-350A for bilateral ventilation

E, ES type oil tank, air pipe head / float type oil tank, breathable cap, 80-350A for bilateral ventilation

D, DS float type oil tank, breather cap, float type oil tank, air pipe head, dimension:

Marine air pipe head ballast tank, air pipe, head oil tank, air pipe, head water tank, air pipe head maintenance:

With the time of sailing and the maintenance of the dock, we can check the damage of the ventilation cap, and replace the internal parts more, for example:

Ballast tank, float cap / ballast tank, air cap, float / ballast tank, breather cap, float plate

Ballast tank, breather cap, float plate, Ballast, tank, air, cap, float

Ballast tank, breather cap, float plate, Ballast, tank, air, escape, heads, float

Ballast tank, air cap, gasket, air pipe head, rubber ring, breathable cap, floating disc, sealing ring, GASKET, for, overflow, ballast, head, RUBBER

Stainless steel bolts support support for floating head float tray

Breather cap side / air pipe head side cover Air, cap, side, cover/Air, pipe, head, side, cover
